Question

A 76.00 pound flask of mercury costs $ 125.50 . The density of mercury is 13.534 g/cm 3 . Find the price of one cubic inch of mercury by calculating intermediate values. What is the price of one pound of mercury?

Answer 1

1 cubic inch cost = $0.80

1 pound of cost = $1.65

Step-by-step explanation:

given data

76.00 pound mercury costs = $125.50

density of mercury = 13.534 g/cm³

solution

we get here 1 pound of cost that is

1 pound of cost =
`(125.50)/(76)`

1 pound of cost = $1.65

or

453.5 gram cost = $1.65

now we get volume of flask

volume of flask = 76 ×
`(453.5)/(13.534)`

volume of flask = 2546.62 cm³ = 155.40 cubic inch

so 155.40 cubic inch cost = $125.50

and 1 cubic inch cost =
`(125.50)/(155.40)`

1 cubic inch cost = $0.80
